Proper way to cut cloth for lamming a fishy tail like this?

General Discussion
1

I’m going to lam a fishy-type tail like this in the next day or two (borrowed this pic from the resin tints thread, more amazing Vader work):

Two main questions:

Do the wings/bumps need a cut in the cloth, or will the cloth conform? Hoping to use 4oz S glass, if that matters. If a relief-type cut is necessary, how / where?

  1. The buttcrack. If I run a cut straight up the crack, I won’t have cloth coverage near the crack on the deck when I pin the laps.

I’m thinking of making an unusual fin patch, perhaps one done in two pieces which I’ll match up at the stringer, and placing that underneath the standard lam layer, so that each half of the tail patch can wrap it’s side of the crack onto the deck.

Just wondering how the masters of glass would approach this.

Thanks for any hints!

I was wondering the exact same thing. It’s funny how someone else usually ask’s it on Sway’s a couple of days later. Sorry, no answer but it’s almost spooky sometimes.

Ummm… well it depends…ummm…case by case thing…ummmm…

With 4 oz you can do the wings without a cut. Use your finger to get it good…but…a small cut and some finger action and a small patch piece might do the trick too…

The butt…more than one way to skin a cat…I cut straight up the crack…and then glass in a G-string…after flipping I use small patches to fill in the gaps…But I’m more ho than pro!!!

Don’t sweat it too much…

Howzit stingray, I do a straight cut then after both sides are lammed I put a hour glass cut piece of glass on which covers both sides(top/ bottom) where there’s no glass. Another way is to lay a patch on the deck and then when you lay down your reinforcement patch on the bottom for the fins run it all the way to the tail and cover that area. Both ways work.Aloha,Kokua

Yeah ,I use an hour glass cut.

Resinhead calls it a g-string.

One time at Keith’s house the wind blew away the small piece of fiberglass and Resinhead was running around yelling trying to find his G-string before the resin kicked off.

…there re no problem really

check whatever fish and look the crack on the deck view…notice that the small part that you refer has other color or its done in the deck lam work

the bottom cloth layer goes to cover the masked area

due to that the masked area is to the crack rail not to the stringer, to say something

Thanks for the replies, everyone! I ended up using a two-piece fin patch and then the g-string from the top layer.

Kensurf, i like your approach. I was wondering how to get the crack the color of the bottom lam, now I know!
